i used small amount of dryer lint thanks for the heads up!Be careful with fillers. Depending on what You use and in a bottle neck case You could end up with an "everybody trying to squeeze into the hole at once" type effect. In short a pipe bomb. A lot of folk who used things to fine like cream of wheat in bottle necks had bad things happen. Try going to something like 4759 and no filler. Ya sure can't 8itch at an inch though
